Plastic Roof Covering (In Preparation)
Please see how to videos online for further clarification
Regardless of which covering will be installed on your building, the success or
failure of the job, and your safety, will often be determined by the
preparation and understanding of the task ahead.
The following is a checklist BEFORE you actually rolling out your cover.
The top edge of your ridge should have been checked for roughness when you
were installing it. Make sure any burrs have been filed down.
If your building is longer than 12’ the ridge will have one (or more)
connectors. These should be wrapped with duct tape.
If your wirelock channel was not installed continuously over the crest, this edge
should also be covered with duct tape.
If your building includes roll-up side walls, the mechanism for securing the
cover at the top of the roll up should be complete before proceeding. (It can be
done later, but is significantly more complicated).
You will require a ladder (or other elevating device) for comfortably reaching
the peak at BOTH ends of your building as well as 2 thin ropes that are a
minimum length of ¾ of your cover width (to assist in pulling the cover over).
Your covering fasteners for the sides should be distributed along the sides
(tucked against the building so as not to get in the way). If you are using spruce
strapping, it saves time if you put all the screws in first. Pre-drilling, as well as
setting screws and washers will save the wood from splitting.
Walk along the side of the building where you will unroll your cover. Check
for and eliminate sharp objects (broken off weeds are especially bad). If an
object can’t be removed, the edges should be covered. If there is absolutely NO
room to roll out the covering along the building, give us a call to discuss “Plan B”.
Four (or more) people to install the cover are advisable if you have never done
this before. It can be done with 2 or 3 but remember, the slower the job goes
the more chance there is of the wind picking up. A couple extra people
during the initial pulling over and squaring is helpful. These extra people can
leave once the cover is tacked in place.
The effect of wind, even a breeze, will be magnified by the size of your cover.
You will be looking at this cover for a long time, wait an extra day if necessary. Early morning or
late evening is usually best time of day.
If your ends are covered in plastic it is definitely easier to do the ends before the roof cover goes
on. This is because the end plastic normally goes UNDER the roof plastic. At the very least it is
recommended to have the end wall framing in place before the roof cover goes on.
If you have a longer building and your cover has come on a cardboard core, make sure you have a
pipe to unwind the roll on.

Roof Covering
Please see how to videos online for further clarification
STEP ELEVEN: If your building has been supplied with roll-up sidewalls,
add the framing member for the top of the roll up now.
STEP TWELVE: Frame in the end walls as required. It is preferable to finish the ends before
putting the roof on. At certain times of the year, calm days are hard to come by. Attach the
cover to the ends and cut required openings.
If the roof cover is already on, it is important to close the “up wind” end first.
See “building ends” pages in installation guide for more information on completing the ends.

put the #14 speed screw in the
bottom of the hoop into the
base bracket
measure for the roll up sides attach the wood for roll up
sides at the end hoop
attach the wood for roll up side
STEP THIRTEEN: Install the wirelock track to the topside of the first and last hoop.
SEE WIRELOCK PAGE IN INSTALLATION GUIDE FOR MORE INFO
It is best to start at the bottom and then kink it as you cross the crown.
Install the cover fastener along the base as well. Ensure to duct tape any edges that
may disrupt or rub against the cover
Follow the written instructions, photos and online videos to ensure
your cover assembly goes smoothly.
If this is the first time you are covering this type of structure, preparation is everything!
STEP FOURTEEN: Whenever possible, roll out the cover along the side of the structure and
pull it over the top from the side. Once the cover is centered, pull it tight from end to end and
secure. Work from the center of the end hoops toward the bottom corners.
If your building has a double cover, make sure that the bottom layer has been temporarily secured at the side
BEFORE pulling over the second layer. The bottom layer should be tight while the top layer should just be snug.

unfold the covering, ensuring
there are no sharp objects around mark the center point on the cover
lay out the covering
BEFORE CONTINUING,
Please read all the check marked pointers to have an overview and
understanding of how you will install the cover. Detailed Photo instructions follow.
It is CRITICAL that you pull and tighten your cover
lengthwise BEFORE doing the sides!
For most, determining the length and width is straight forward, but if your
parts list shows a roof covering close to square, verify that the way you
have it rolled out is a minimum of 1’ longer than your building.
Determine the leading edge corners of your cover. Grab the corner,
making about a 12” “tail”. Wrap a rope TWICE around the tail, making a
simple tight knot. Take the opposite end of each rope and go to the top of
the ladders that you’ve leaned against the peak of the building.
ALWAYS pull the cover to the peak BEFORE the person on the
ground continues pulling. Until the whole cover has crossed the ridge,
pull back and forth, lengthwise, in sort of a “sawing” motion.
Continue to feed the cover over until it is centered on the building.
Precision to the inch is not necessary. Judging straightness is simply a
matter of eyeing a fold to one of the purlins. Longer covers will require
someone helping it along half way down the side.
Install 12” of wire insert at each side of the ridge, unless you are
positive you will not have to adjust it. Put in the rest when any
adjustments are made. Don’t allow more than 6” of overhang on the
cover.
Go to the opposite end and pull the cover as tight as you can lengthwise.
For pulling tight, do not use anything more than human power on the
cover wrapped on a short piece of 1x2 strapping. Having many eople
pulling on a hot summer day can create a problem of the cover being
too tight.
Install a piece of your cover fastener half way down each side of the
baseboard. Look along a crease to make sure it is straight. If your building
has roll-ups, “doing the side” refers to the top of the roll-up.
Usually the ends of the cover have been cut squarely. Before proceeding,
verify that you have enough material for all four corners. Make
adjustments needed.
For a double cover, repeat the above steps paying special attention to not
rubbing the rope over the cover over the ridge.
Work from the centre to the ends, working the two sides simultaneously.
As you approach the end you may need to pull lengthwise as well as down.
If the wind starts picking up, work into the wind or upwind first. If a wrinkle develops, always pull at
90 degrees to the mid point of the wrinkle.
If you are putting a double cover on, only pull on the inside layer for tightness. The outside layer needs
a little slack. If you are putting the cover on in extreme cold you will need to tighten the cover once you
have warm weather. Excess roof cover can be trimmed to 2-3 inches once you are certain it is extra
and has had a chance to settle. PLEASE NOTE: Any italicized words in this document are words that are listed in the glossary
STEP FIFTEEN: Fasten the cover to the base
PLEASE NOTE: Any italicized words in this document are words that are listed in the glossary.
prepare to lift the cover onto the
structure
pulling the cover over from the
side, everyone takes a point of
the cover to spread it out evenly
lift it up, being careful not to
snag on anything, more hands
make it easier
ensure cover is centered pull the cover over and make
sure it is all even and straight pull to the end of the structure
pull the cover tight as the wirelock is going in, start putting in wirelock at the ridge first
keep the cover tight as you are working your way down with the wirelock
ensure the screws are in the
1x2 to prepare for fastening
the cover to the base
sandwich the cover between the 1x2 to secure,
complete this sandwiching technique for both sides
of the structure
